Programmatically modify user quota I have already configured my server to work with user quotas and everything works well. I can modify user quota with the `edquota` command. How can I do this programmatically, from a bash script for example?

Use `setquota`.

In the simple form the command is


setquota _user blockquota blocklimit inodequota inodelimit filesystem_

E.g.


setquota foo 10G 10G 0 0 /data


to set both the soft quota and hard limit to 10 GB and no inode limit for user `foo` on `/data`.

I suppose you could use `quota -u $username` to get the current quotas, but I'm not sure how easy that is to parse with a script.
